So hmmm check the picture below
in an isosceles triangle, two sides are equal, and thus the angles those twin legs make, are also twin angles
let's say the angle made is "a", so all internal angles will be 64 + a + a = 180
or 64 + 2a = 180
thus 2a = 180 - 64 => 2a = 116, thus a = 116/2
Answer:
88 sq.in
Step-by-step explanation:
<u>Area of trapezoid = 1/2 (b1 +b2) x h</u>
<u>In this figure:</u>
b1 = 18 in, b2 = 4 in, h = 8 in
<u>So:</u>
A = 1/2 (18 + 4) x 8
A = 1/2 (22) x 8
A = 11 x 8
A = <u>88 sq.in</u>
21.5 means 21 and 5 tenths and is read that way.
21.5 = 21 5/10 =(21*10 + 5) /10 = 215/10 = 43/2 in simplest terms
Answer: anyway i hope this will help
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. Corresponding sides of similar polygons are in proportion, and corresponding angles of similar polygons have the same measure.
Step-by-step explanation:
Formal notation. The wavy line symbol means 'similar to'.
Rotation and reflection. Polygons can still be similar even if one of them is rotated, and/or mirror image of the other. In the figure below, all three polygons are similar.
